Title: Improvements in or relating to the manufacture of Electric Discharge Lamps
IPC: H01J61/14
Filed: 1967-04-18
Abstract: 1,184,691. Metal-vapour lamps. CLAUDE PAZ & VISSEAUX. 18 April, 1967 [18 April, 1966; 16 Nov., 1966], No. 17842/67. Heading H1D. A process for the manufacture of an electric discharge lamp comprising a discharge tube having an ionizable atmosphere containing a rare gas and the vapour of a metal or alloy or compound of a metal includes the step of introducing into the discharge tube a hydrocarbon or halohydrocarbon which will produce, during the operation of the lamp with the temperature of the coolest internal surface of the discharge tube at least 500‹ C., an organometallic compound whose saturated vapour pressure is higher than that of said metal or alloy or compound of a metal. The emission of low-volatility elements, e.g. alkali metals, is thus increased at low lamp loadings and extends over the whole discharge path with no formation of opaque deposits. The lamp is also suitable for pulse operation, e.g. for pumping lasers. Saturated or unsaturated aliphatic hydrocarbons, e.g. ethylene or acetylene, may be introduced under a partial pressure of 0À1 to 10 mm. Hg. Halohydrocarbons may be introduced under a partial pressure of 0À1 to 50 mm. Hg. The metal vapour may be that of indium, mercury, the alkali metals, the alkaline earth metals, the rare earth metals, or the transition metals Y and Sc. Two methods of carrying out the process are described. In the first method, the discharge tube is sealed before operation. Examples of suitable fillings are (a) a drop of mercury alloyed with indium, argon at a pressure of 20 mm. Hg and ethylene bromide at a pressure of 10 mm. Hg and (b) mercury, thallium iodide, indium iodide, sodium iodide, argon at 20 mm. Hg and ethylene at 0À25 mm. Hg. In the second method, a discharge is maintained in the tube for about 1 min. before it is sealed off. The tube containing mercury, iodides, argon and a hydrocarbon is connected to a vacuum duct through a stem surrounded by a cold trap (Fig. 2, not shown). Following the discharge the tube is allowed to cool until the volatilized products have completely condensed and the gaseous atmosphere is pumped out. The tube is then filled with argon at a pressure of 20 mm. Hg. Finally, the cold trap is heated to drive condensed products back into the tube which is then sealed off. In this method hydrogen may be introduced with the original filling to prevent the formation of carbonaceous deposits during the discharge treatment.

IPC: C07F9/201
Filed: 1956-06-12
Abstract: Esters of thiophosphorous acid of the general formula: <FORM:0797970/IV (b)/1> where R and R1 represent any organic residues, are prepared by reacting a compound of the general formula: <FORM:0797970/IV (b)/2> with hydrogen sulphide in the presence of an agent capable of binding hydrogen halide, especially a tertiary base such as dimethylaniline, triethylamine or pyridine.  R and R1 may be aliphatic residues, straight or branched, saturated or unsaturated, possibly substituted as in chlorethyl or by thiocyano, cyano or ester groups; aromatic residues such as phenyl, chloraryl, nitro-aryl, alkoxyaryl, naphthyl, di-phenyl; araliphatic radicals such as benzyl; or cycloaliphatic or heterocyclic radicals.  Preferred are dialkyl chlorophosphites, especially diethyl chlorophosphite.  The reaction is advantageously carried out at room temperature or a moderately raised temperature and in an inert diluent such as benzene, toluene, chlorobenzene, ketones, e.g. acetone or ethers, e.g. diethyl ether, tetrahydrofuran.  The products are intermediates for the synthesis of pesticides.  In examples an ethereal solution of the corresponding chlorophosphite is reacted with H2S in the presence of pyridine to yield diethyl thiophosphite, dimethyl thiophosphite, methyl dodecyl thiophosphite, ethyl cyclohexyl thiophosphite, benzyl ethyl thiophosphite, phenylethyl thiophosphite, tetrahydrofurfuryl ethyl thiophosphite, and ethyl ethylthioethyl thiophosphite.  In Example (3) an ethereal solution of diethylchlorophosphite used as a starting material in the above reaction is prepared from ethyldichlorophosphite by reaction with ethyl alcohol in the presence of pyridine.

Abstract: 375,997. Holders for use in slicing meat. KAY, J. R., 16, Bolton Road, Bury. June 24, 1931, Nos. 18231 and 32067. [Class 28 (ii).] A device for holding skewers 15 for securing meat in position upon a butchers' board 6 has means for guiding the skewers in a definite and constant direction and for preventing lateral movement of the skewers without engagement in the wood of the board of the skewer points. The device comprises a frame member 13 supported by pillars 12 the ends whereof are clamped slidably to the board or to a table whereon the board rests. The member 13 is so bored at 14 and is of such a depth that the skewers are guided down and held in the meat against movement. Lateral movement may also be prevented by providing a baseplate 9 on the board with orifices 16 to engage the skewer points and also prevent them entering the board. The skewers may carry collars limiting their descent or their ring heads 15a may suffice for this purpose. The frame member 13 may be bent to remove the pillars 12 out of the way of the cutting knife, or the skewers may be mounted on arms projecting from the member 13. According to the first Provisional Specification the skewers may be mounted in pedestals and the board may be tapped to accommodate screwed detachable hollow metal members for receiving the skewer points.

Title: Improvements in or relating to the production of derivatives of ª‰-erythroidine
IPC: C07D491/20
Filed: 1944-09-25
Abstract: A tetrahydrogenated derivative of b -erythroidine is produced by hydrogenating b -erythroidine or an acid salt thereof, e.g. a hydrohalide, in the presence of a hydrogenation catalyst, e.g. platinum oxide, until approximately two mols. of hydrogen are consumed per mol. of starting material.  The hydrogenation may be effected in slightly acidic aqueous solution or in anhydrous dioxane solution with hydrogen at a pressure of 10-40 pounds per sq. inch. After hydrogenation, the tetrahydrogenated product is neutralized to pH 7.0 to 7.5 and extracted with a water-immiscible solvent.  b -Tetrahydro-b -erythroidine is obtained from this mixture of isomeric-b -erythroidines by treating with an acidulating agent, separating the mixture of crystalline salts thus obtained and isolating the salt of b  - tetrahydro - b  - erythroidine by selective solvent extraction, e.g. absolute ethanol.  Salts which may be formed for the purpose of separation are perchlorates, hydrobromides, hydrochlorides or salicylates. In examples: (i) b -erythroidine hydrochloride in aqueous solution is hydrogenated using a platinum oxide catalyst to obtain b -tetrahydro-b -erythroidine; (ii) b -erythroidine in anhydrous dioxane is hydrogenated using a platinum oxide catalyst to obtain b -tetrahydro-b -erythroidine; (iii) b -tetrahydro-b -erythroidine prepared as in example (i) is converted into the perchlorate; (iv) the perchlorate obtained in example (iii) is converted into the hydrochloride; (v) b -tetrahydro-b -erythroidine is recovered from its hydrochloride and purified by recrystallization; (vi) the product of (v) is converted into b -tetrahydro-b -erythroidine salicylate.
